Abstract

As part of an analysis of a VSC-HVDC operating in parallel with AC transmission lines, this paper presents an adaptive control of VSC-HVDC that allows the device: to provide voltage support by means of reactive control at both ends; to damp power oscillations and improve transient stability by controlling either active or reactive power; and to control the power flow through the HVDC link. Simulations showed that the control operated correctly and that the VSC-HVDC significantly contributed to voltage stability, damping of power oscillations and improving of transient stability
